OpenOffice.org only (Windows/Mac/Linux): The Sun PDF Import extension imports and edits PDFs with the free Microsoft Office alternative OO.org. Rather than import the PDFs into the Writer program, the extension works with OO.org's Draw application. Once imported, you can still edit text or other portions of the document. The extension isn't perfect, but it appears to be under active development and could come in really handy under the right circumstances. The Sun PDF Import extension is free, works wherever OpenOffice.org 3.0 does.
